LEED Performance Report

2. ACKNOWLEDGEMENTS
The following Performance Reports were created in accordance with Council Resolution 20071129-045. The
City of Austin is a recognized international leader in sustainable building practices in which municipal building
strive to conserve energy, water, and other natural resources while promoting human health and safety. The
holistic approach to architecture creates high-quality and enduring structures that enhance the economic
value and reduce the lifecycle costs of a building.
Design and construction of buildings are driven by the United States Green Building Council’s (USGBC)
Leadership in Energy and Environmental Design (LEED) guidelines and promote these goals. The following
reports provide information about municipal buildings, highlight LEED credentials, and promote sustainable
building achievements.

6708 North FM 620, Austin, TX 78730
LEED BD+C: New Construction v2.2
AWARDED LEED SILVER
DECEMBER 2019
Negrete & Kolar Architects
Water Treatment Plant 4, Austin’s newest water treatment plant facility, supports the city’s drinkable water
infrastructure by treating 50 million gallons a day (mgd), with the potential to expand up to 300 mgd. WTP4’s LEED
Silver Certified Maintenance Building is built within the facility’s vicinity to access, restore and improve every part of
the plant and its services to an acceptable standard and to sustain the utility and value of the facility. This includes
day-to-day services necessary to maintain the main plant at WTP4, usage of the building’s systems and equipment, as
well as the occupants/users that will be operating within the facility. The other main building on the campus is the
Administration office which has achieved a separate LEED certification to gold level.
In order to minimize energy consumption, the Maintenance Building has been divided up into cooling and heating
zones in the usage of various functional spaces. An example of this can be seen in the electrical and office spaces,
which include heating and air-conditioning units, while the warehouse area is limited to heating and ventilation only.
The roof of the building also exemplifies an area that has implemented measures to reduce the overall energy
consumption by installing rooftop energy recovery ventilators. The ventilators connect directly to a new or existing
rooftop unit and does not require any additional roof penetrations.

100% of energy is generated from electricity
from offsite renewable energy.
This building is on GreenChoice 100% renewable
energy powered by West Texas wind for 3 years.
Encourage the development and use of grid-
source, renewable energy technologies on a net
zero pollution basis.

REDUCES POTABLE WATER USE
Rotating Stream Sprinklers are responsible for about
30% of the reduction in irrigation potable water use.
High-efficiency water fixtures allow more water flow
with less energy use and provides a sustainable
alternative to conventional systems
Potable water is a valuable resource that can be
significantly reduced in the design phase of a building

DIVERTS MATERIALS FROM LANDFILL
Minimizing materials going into landfills
through reuse, salvaging, and recycling are
ways to conserve natural resources
Reducing the amount of material needed and
recycling content can significantly decrease waste
Prefabricated components are a great method of
reducing material scraps and packaging

Over $205,000 of the material is regionally
purchased from within 500 miles of the site

AARC provides appropriately sized dedicated areas for the
collection and storage of materials for recycling, including
cardboard, paper, plastic, glass, and metals
On-site waste and single stream recycling receptacles are
collected by facility staff then taken to collection points
